How Dehydration impacts your eyes?

DEHYDRATION:

PRIME CAUSE – NOT DRINKING ENOUGH WATER

Dehydration occurs when the body does not have enough fluid. As a critical element of the body, water is needed for various organs to function. When the body is not adequately hydrated, organs, including the eyes, suffer.

Dehydration is when more water leaves the body than enters the body. This typically happens when people stop drinking water or lose large amounts of fluid. Fluid loss occurs in daily bodily functions such as sweat, urination and bowel movements. Extreme heat, vomiting, diarhoea, alcohol and even diabetes increase the risk of dehydration.

 

Symptoms of dehydration

 

The body’s initial response to a loss of fluid is to preserve the amount of fluid still in the body by conserving water. This leads to various symptoms of dehydration including thirst and dry mouth, decreased urine output, muscle cramps, headache, light-headedness, sleepiness and a lack of tear production. When the eyes stop producing tears, they are no longer properly lubricated, which can lead to dry eye, eye strain and vision problems.

Eye Dryness

Dry eye occurs when there are insufficient tears to nourish the eye, and tears are necessary for providing clear vision. Tears wash away foreign matter in the eye and help reduce the risk of eye infections. Symptoms of dry eyes include irritation, excess watering, blurred vision and feeling foreign matter in the eye. As a symptom of dehydration, the best treatment for dry eye is rehydrating by drinking plenty of water. Eye drops can also help alleviate the symptoms by lubricating the eye and washing away foreign materials.

 

Tired eyes, blurred vision, headaches and double vision are all symptoms of eye strain. As with dry eye, eye strain caused by dehydration can result when the eye is not properly lubricated. Additionally, eye strain is also caused by concentrating on visual tasks or while using a digital device for an extended period of time. If caused by dehydration, drinking plenty of water will help flush out salt in the body and properly hydrate your eyes to help reduce eye strain. Resting the eye by blinking or shutting the eye will also help alleviate eye strain.

 

How to manage dehydration, to help ease the pain of digital eye strain.

You can prevent dehydration by drinking plenty of water throughout the day. It is especially important to intake fluid before, during and after exercise to replenish the water lost through sweating. Other tips for preventing dehydration include removing excess salt from your diet and reducing intake of alcohol, caffeine and high-protein foods.

Ultra violet (UV) rays

How does Ultra violet (UV) rays affect my vision??

Sunlight is major source of UV rays.

There are 2 types of UV rays namely UV-A and UV-B. Over time UV rays may cause number of eye problems.

UV-A
can hurt your central vision. It can damage the macula, a part of the retina at the back of your eye.

UV-B
The front part of your eye (the cornea and the lens) absorbs most UV-B rays, but these rays may cause even more damage to your eyes than UV-A rays

 

Macular Degeneration

UV rays may lead to macular degeneration, a leading cause of vision loss.

Cataract

UV rays, especially UV-B rays, may also cause some kinds of cataracts. A cataract is a clouding of the eye’s natural lens, the part of the eye that focuses the light we see.

Pterygium

Another UV-related problem is a growth called pterygium. This growth begins on the white of the eye and may involve the cornea. Eventually, the growth may block vision. It is more common in people who work outside in the sun and wind.

Skin Cancer

Skin cancer around the eyelids is also linked to prolonged UV exposure.

Corneal Sunburn

Corneal sunburn, called photokeratitis, is the result of high short-term exposure to UV-B rays. Long hours at the beach or skiing without proper eye protection can cause this problem. It can be very painful and may cause temporary vision loss.

 

How to protect your eyes from UV rays

 

  • Always use goggles whenever you are in sunlight.
  • Use of transition lenses of good quality helps a lot to reflect back UV rays from your spectacles/ glasses.
  • There are certain light sources even at home which emit UV rays, replace them with the non-harmful ones.
  • Use of polarised sunglasses also helps to protect against UV rays

Risk and complications of Lasik can be treated successfully by medical treatment or minor touch up procedures in most of the cases.

Treatment of Lasik Risks and Lasik complications

  1. Dry Eyes after Lasik: drink enough water (weight X 40= water in ml e.g. 60 kg X 40 = 2400 ml / 2.4 lit). Use lubricating eye drops or immune modulator eye drops like Cyclosporin

  3. Enhancement: for remaining number (under correction or over correction)
  4. Lasik Flap folds or wrinkles: repositioning flap with mild Lasik Flap Ironing and contact lens for 1-2 days
  5. Lasik Flap displacement: repositioning of flap with contact lens for 1-2 days
  6. Epithelial Ingrowth: cleaning surface with medicated solution
  7. Infection: Use of 4th generation antibiotics for infection control
  8. Diffuse Lamellar Keratitis (DLK) or “Sands of Sahara”: use of anti-inflammatory medications and in advanced cases cleaning flap
  9. Keratectasia or Keratoconus: Avoid eye rubbing, scleral contact lens, C3R & Intacs
  10. Decentred Ablation: not seen these days due to use of active eye tracking and Iris registration by New generation Lasers used all over world. It was occurring in few cases when passive eye tracking method was used.

    • Corneal aberrations (abnormalities )
    • Corneal curvature (shape of cornea , topography, pentacam)
    • Thickness of cornea or Pachymetry
    • Retina examination

Once all these tests results are favourable and positive one can go to next level i.e. surgery.

  1. An experienced lasik surgeon will guide you only on the basis of the testing which are done prior. Because it is very important for your eyes to undergo personalized treatment which has best results and no side effect after the procedure.
